Software Engineer - Compiler

About the Role

Sigma Computing is redefining business intelligence by making complex data analysis accessible through a high-performance platform built for the modern data stack. The Compiler Team plays a foundational role in this mission by transforming user-driven spreadsheet interactions into highly optimized SQL queries, enabling seamless exploratory analytics on cloud data warehouses. As a member of the Compiler Team, you will join a group of engineers dedicated to building the core systems and abstractions that power Sigma’s intuitive spreadsheet interface, ensuring speed, reliability, and scalability for all users.

What You Will Be Doing

• Tackle core challenges at the intersection of data modeling, query compilation, and large-scale interactive analytics—making it possible for end-users to query data warehouses efficiently without deep technical knowledge
• Design, build, and maintain sophisticated compiler infrastructure and intermediate representations that translate spreadsheet operations into optimized query plans
• Apply advanced optimization strategies to improve performance and accuracy across a wide range of query workloads and data architectures
• Contribute to both backend (Rust) and key frontend foundations (TypeScript), evolving critical abstractions that enable end-to-end workflow optimizations and new features
• Debug, analyze, and resolve complex issues, ensuring robustness and maintainability in a rapidly evolving product
• Collaborate with engineers and product stakeholders to review designs and code, driving technical best practices and architectural decisions throughout the team and company

Qualifications We Need

• 5+ years experience engineering high-quality software systems
• Demonstrated success building and maintaining complex infrastructure or core platform services
• Deep understanding of Computer Science fundamentals, particularly in compilers, algorithms, SQL Optimization
• Passion for teamwork, technical ownership, and continually raising the engineering bar
• Experience working in an iterative, high-cadence environment

Qualifications We Want (also, skills you’ll learn!)

• Exposure to distributed systems, query optimization, or database internals
• Experience with API or data model design in the context of high-performance cloud services
• Familiarity with cloud infrastructure (e.g., GCP, AWS, Azure)
• A curiosity for new languages and tools, and a drive to solve challenging problems at scale (Rust, Go, Node, K8s, GraphQL)

Additional Details

• Base salary range: $170k - $235k annually
• Work environment: In-office work environment in SF with a 25% travel expectation unless explicitly stated otherwise
